because I find his books extremely difficult to remember by title

Oh, same. It's a lot easier to describe them as "the one where the hero is a toymaker" or "the one set in the USSR." (That is slightly cheating because the one set in the USSR is one of the few where the title is actually meaningful to the plot, but the one where the hero is a toymaker really isn't.)

but I'm sure that at least some of these are new to me and others I haven't read in a while, so I'm looking forward to this!

Hooray! Enjoy!
